Has anyone or does anyone know how to install a cd player into a 91 silverado with the cassette player/equalizer in the center of the dash? I am having difficulty even finding the wiring harness. If this is not possible, does it work to run a line off the rear speaker wire to the inputs on the amp? Obviously not as good of sound, but possible?

 

I've done it before. Total pita. You should check to see if metra makes a harness. Pretty sure they do. Then you can use a oem-1 for the amp hook-up.

 

Its no big deal. 99-3000X dash kit from Metra (X = Color of Dash). 70-1858 Harness. 40-GM10 Antenna Adapter. Go behind the ash tray, you'll locate the tuner pack. It's right there. Piece of cake once you get to it. Metra also makes a pocket so you don't have to leave the sqare radio in the dash. Can't remember the Part #.

 

A 91 chevy is about the easiest install there is. Just get the metra kit and the wireing harness
